Omegon Head Mirrors -<\/strong> Razor-sharp images in a large Newton<\/strong>
This 12\u2033 F\/5 mirror set is perfect for self-building a Newton mirror telescope. The 300 mm main mirror captures a lot of light, making even faint deep-sky objects visible. Together with the matching capture mirror, you'll enjoy sharpness and contrast across the entire field of view.<\/p>\n\n\n\n

\"Omegon<\/figure>\n\n\n\n

High quality materials and coatings<\/strong>
The main mirror is parabolic and made of borosilicate glass for stability and precision. The catch mirror is flat and elliptical with a small axis of 70 mm. Both mirrors have aluminum and SiO\u2082 coatings that guarantee maximum reflection and color purity.<\/p>\n\n\n\n
